These are baking vessels, typically made of steel, characterized by their rectangular shape, high sides, and seasoned finish. They are integral to producing a specific type of pizza known for its crispy, lacy-edged crust and airy interior. For example, a 10×14 inch, dark-colored pan with sloped sides is commonly employed for this purpose.
The utility of these implements extends beyond merely containing the ingredients. The material and construction contribute significantly to the unique textural qualities of the resulting pizza. The high sides promote deep-dish characteristics, while the steel facilitates even heat distribution and the development of a caramelized crust. Historically, these pans often repurposed industrial parts trays, contributing to the pizza’s distinctive form.
